Answer:
<h3>Q = Mt</h3>
Step-by-step explanation:
It's too hard for me to show all the work, but you can find a common denominator in 8.
Change 3/4 to 6/8 and -3/2 to -12/8.
Now that all the fractions have the same denominator, you can multiply the whole problem by 8 and cancel out all denominators.
You are left with 6=3x-12
Add 12 to 6 and cancel out on the right side.
18=3x
Divide by 18 by 3
x=6
Answer:
Y-12 + y =120 take 12 to the other side get 2 y = 132
Y=66 so y-12=x
X=54
Division by zero is undefined. That is a impossible question
